Constructible on arbitrary knots, they\nextend the standard P-splines of Eilers and Marx (1996)\n. They are also related to the\nO-splines of O'Sullivan (1986) via\na sandwich formula that links a general difference penalty to a\nderivative penalty. The package includes routines for setting\nup and handling difference and derivative penalties. It also\nfits P-splines and O-splines to (x, y) data (optionally\nweighted) for a grid of smoothing parameter values in the\nautomatic search intervals of Li and Cao (2023)\n. It aims to facilitate other\npackages to implement P-splines or O-splines as a smoothing\ntool in their model estimation framework.", "License": "GPL-3", "NeedsCompilation": "yes", "URL":
